Abstract

A particulate material delivery system for an agricultural implement including, an inductor box configured to receive particulate material from a tank, the inductor box including, an inductor segment comprising a particulate material supply chamber configured to guide the particulate material toward a fluidization chamber, and an air supply chamber configured to receive airflow from an airflow supply, wherein the inductor box is configured to direct the airflow from the air supply chamber to the particulate material supply chamber through a first airflow path and through a second airflow path remote from the first air path.

First claim

The invention claimed is:

1. A particulate material delivery system for an agricultural implement comprising:
a first screen and a second screen;
an inductor segment comprising a particulate material supply chamber configured to receive a particulate material from a particulate material tank;
an upper airflow path configured to direct an airflow from an airflow supply through the first screen into the particulate material supply chamber; and
a lower airflow path configured to direct the airflow from the airflow supply through the second screen into the particulate material supply chamber;
wherein the particulate material supply chamber comprises an inlet and an outlet, the inlet is configured to receive the particulate material from the particulate material tank, the outlet is configured to expel the particulate material, and the lower airflow path is substantially parallel to the outlet of the particulate material supply chamber.

2. The particulate material delivery system of claim 1 , wherein the upper airflow path is non-parallel and non-perpendicular to the inlet of the particulate material supply chamber.

3. The particulate material delivery system of claim 1 , wherein the inlet and the outlet of the particulate material supply chamber are substantially perpendicular to one another.

4. The particulate material delivery system of claim 3 , comprising a tank airflow path configured to direct the airflow from the airflow supply through the first screen to the particulate material tank.

5. The particulate material delivery system of claim 1 , wherein the inductor segment comprises a fluidization chamber configured to receive the particulate material from the particulate material supply chamber.

6. The particulate material delivery system of claim 1 , wherein the upper airflow path and the lower airflow path are remote from one another.

7. The particulate material delivery system of claim 1 , wherein the upper airflow path is configured to direct the airflow from the airflow supply into the particulate material supply chamber via the inlet.
